After receiving my order, I decided to research lazasine more thoroughly. It's not a common stone, so there wasn't a lot to find, but what I did find made me concerned about the beads being treated, not treated. I emailed customer service to get reassured, but I only received a curt reply stating that the beads could pass any lab testing. The company knows good and well that the average customer doesn't have access to, or can't afford, lab testing.. so that doesn't sit right with me. I distrust Intrinsic and won't buy from them again.
